SCAFFOLD.

Application filed April 28, 1927. Serial No. 187,305.

This invention relates to scaffolds adapt ed to position a stage orplatform against its work to prevent swinging.

An object of the invention comprehends hanging arms for supporting theplatform.

Another object of the invention contemplates means for adjusting aplatform upon the hanging arms.

A further object consists of a brace n1echanism to assure rigidity ofsupport.

More specifically stated the hanging arms are provided with stepmembers.

With the above and other objects in view, the invention further consistsof the following novel features and details of construction to behereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claim.

In the drawings:

Figure 1 is an elevation of the invention while in use.

Figure 2 is afront elevation thereof.

Figure 3 is a transverse sectional view taken on line 33 of Figure 2.

Figure 4 is a vertical sectional view taken on line 4.% of Figure 2.

Figure 5 is a horizontal section taken on line 55 of Figure 1.

Referring to the drawings in detail, wherein like characters ofreference denote corresponding parts, the reference characters 10indicate hanging or supporting arms provided with curved ends'll adaptedto be extended over the cornice, ledges, sills and other portions of abuilding structure suitably anchoring said arms.

Step or tread members 12 are carried at spaced intervals along thelengths of the arms and disposed in staggeredrelation to accommodate thefeet of an operator when ascending or descending upon the arms. Aplatform or stage such as indicated at 13 is provided with pivoted links14: upon the opposed sides thereof and upon the bolsters therefor.Clamping sleeves 15 slidably mounted in superimposed relation upon thearms 10 have pivotally mounted between ears carried thereby the adjacentends of the links 14. Sleeve members 16 slidably mounted upon the arms10 are held at deadapted to anchor the sired heights thereon byfastening elements passed through opei'iings arranged at spacedintervals in the lengths of the arms. Clamping sleeves, 17 are carriedby the sleeves 16.

Pivoted links 18 intersecting and pivotally connected at intermediatepoints in their lengths have the outer-most ends thereof pivotallyconnected wvitli the clamping sleeves 17. bolsters of the platform orstage 13 are adapted to receive appropriate portions of the upperextremities of the links 18 to space the arms 10 in parallelism with theside of a building to repose the adjacent end of the stage or platformthereagainstto overcome swinging. I

hen the stage or platform 13 is shifted for an appreciable distance itis to be noted that the normal arrangement of the links 14 and sleeves15 would tilt the same and to overcome this diiiiculty the sleeves 15are reversed from the normal positions.

It is to be noted that the platform and brace mechanism may be raised toa desired height and locked in such position by the aforementionedfastening elements passed through the arms.

The invention is susceptible of various changes in its form, proportionsand minor details of construction, and the right is herein reserved tomake such changes as properly fall within the scope of the appendedclaim.

Having described the invention, what is claimed is:

A sc liold etmiprising vertical arm members provided with curved upperends same upon its work, a platform, sleeve'n'iembers slidably mountedupon the arms immediately beneath the platform,.a pair of verticallyspaced clamping sleeves carried by each of the sleeve members, crossedlinks pivoted together intermediate their ends and having their endspivoted to the clamping sleeves, and tooth bars depending from theplatform and being adapted for engagement with the pivoted links toregulate the platform horizontally of the arms.

In testimony whereof I afiix my signature.
